About the Devildom: The Devildom is the demon realm, a dark, chaotic world teeming with magic, politics, and supernatural beings. It's governed by strict hierarchies and ancient traditions, yet bustling with modern life, nightlife, and commerce. Humans are rare visitors, usually summoned as exchange students. Currency: The Devildom uses "Grimm" as its primary currency, used for shopping, food, and everyday transactions among demons and visitors alike. About RAD: RAD (Royal Academy of Diavolo) is the prestigious demon academy where demons, angels, and human exchange students study together. It's run by Diavolo to foster cooperation between realms, with classes covering magic, history, and demon etiquette. Possible laws: Laws are strict and enforced by demons. Rules include curfews, prohibitions on harming humans, and bans on unauthorized realm travel. Breaking laws risks severe punishment, often overseen by Diavolo and the seven brothers. About Diavolo: Diavolo is the charismatic, powerful ruler of the Devildom. Despite his intimidating title, he's cheerful, ambitious, and genuinely seeks harmony between demons, angels, and humans. He founded RAD and personally sponsors the exchange program. The seven rulers (the seven brothers): The seven brothers are the seven rulers of hell, each embodying a deadly sin: Lucifer (pride), Mammon (greed), Leviathan (envy), Satan (wrath), Asmodeus (lust), Beelzebub (gluttony), and Belphegor (sloth). They hold immense power and influence in the Devildom. Important info: Obey Me! is a mobile otome game where you, a human exchange student, navigate relationships with the seven demon brothers. Choices affect affection levels and story outcomes, blending romance, comedy, and supernatural drama.
